For decades, a specter has haunted the U.S. economy: the specter of surging gas prices. From the malaise years of the 1970s to the early 21st century spike when a gallon of gas climbed from $0.90 in 1999 to more than $4 a gallon in 2008, family's lived in fear that we were one Middle East conflict away from another painful bite into our paycheck.

But what if I told you we could end that pain with one word. Fracking.

Hydraulic fracturing (a.k.a.: fracking) is the drilling technology that has produced a slew of cheap domestic natural gas. Some energy analysts suggest that it could do the same for oil and gasoline. That sounds crazy. Here's why it might not be.

Getting oil from earth crust to car is an arduous process that makes it susceptible to price surges. Oil fields have to be discovered, wells dug, pipelines constructed, and refineries erected. Each one of these investments is enormously expensive. Once in place, the system can produce constant flow for decades: up the well, down hundreds of miles of pipeline, into a refinery's distillation tower, through a series of chambers for oxygenation and blending, and ultimately poured out as consumer-ready gasoline.

Oil recovery and refinement is a marvel of engineering, but a disruption in the process can be catastrophic. Wars, embargoes, or refinery fires could shut down that flow, and nothing can be done in the near term to replace it. Gasoline stockpiles collapse, prices rise, and that familiar American syndrome would settle in.

It's not natural gas. It's fracked oil.

Fracking is altogether different. It's not just an innovative way to get at previously unreachable oil reserves. It alters the very nature of the oil and gasoline supply chain.

A traditional well might produce 50 barrels of oil a day when it opens, but it will produce close to that for more than a generation. Newly fracked wells have been known to produce over 7,000 barrels a day. That torrent will slow to a trickle in as a little as 18 months, but the rush of oil fundamentally changes the dynamics. OIl is produced so quickly there often isn't time to lay pipelines. Much of the oil from North Dakota's prolific Bakken Shale has made it to market by train.

Train transport is more expensive, but it also more flexible. Pipelines have a fixed destination, but tanker cars can unload anywhere a terminal is designed to accept oil. These facts -- gushing wells and flexible delivery by rail -- mean that fracked oil operations function more like a just-in-time service than a decades-long industrial investment.

The oil itself is also different in composition. Traditional crude is thicker and heavier. Refineries are designed to make the most out each barrel, separating out the light components (which become gasoline) medium components (diesel fuel and kerosene), and heavy components (asphalt).

Fracked oil rarely contains heavier molecules. Much of it nearly qualifies as natural gasoline, a descriptor typically applied to certain liquids extracted at natural gas processing facilities. Natural gasoline, as the name suggests, is very close to the stuff you that you put in your car and requires relatively mild refining and blending before it can be sold at the neighborhood gas station. For fracked oil, the heavy-duty refining operations designed for conventional oil are overkill.

As a result, older East Coast refineries that were once slated to be shut down -- like Sunoco Philadelphia -- have been revived as destinations for fracked crude. These refineries cannot compete with the sophisticated operations on the Gulf Coast and Midwest when it comes to processing thicker grades, but they can handle the light, fracked oil just fine.

This new oil production chain is still maturing, but it promises exactly what gasoline consumers have longed for: an industry that responds to shortages with increased supply rather than increased prices. In Eagle Ford, operators have been able to drill wells in as little as 10 days. Within a month those wells will produce millions of barrels of oil. That oil can be delivered by tanker car to just about any refinery in the nation and processed into gasoline.

Crises will continue to erupt and global oil supplies will continue to be threatened. Yet, now we have the means to fight back. The production of gasoline from domestically sourced, hydraulically fracked oil can be ramped up within months, and ever increasing pain at the pump can finally be relieved.

His paranoid style paved the road for Trumpism. Now he fears what’s been unleashed.

Glenn Beck looks like the dad in a Disney movie. He’s earnest, geeky, pink, and slightly bulbous. His idea of salty language is bullcrap.

The atmosphere at Beck’s Mercury Studios, outside Dallas, is similarly soothing, provided you ignore the references to genocide and civilizational collapse. In October, when most commentators considered a Donald Trump presidency a remote possibility, I followed audience members onto the set of The Glenn Beck Program, which airs on Beck’s website, theblaze.com. On the way, we passed through a life-size replica of the Oval Office as it might look if inhabited by a President Beck, complete with a portrait of Ronald Reagan and a large Norman Rockwell print of a Boy Scout.

“Well, you’re just special. You’re American,” remarked my colleague, smirking from across the coffee table. My other Finnish coworkers, from the school in Helsinki where I teach, nodded in agreement. They had just finished critiquing one of my habits, and they could see that I was on the defensive.

I threw my hands up and snapped, “You’re accusing me of being too friendly? Is that really such a bad thing?”

“Well, when I greet a colleague, I keep track,” she retorted, “so I don’t greet them again during the day!” Another chimed in, “That’s the same for me, too!”

Unbelievable, I thought. According to them, I’m too generous with my hellos.

When I told them I would do my best to greet them just once every day, they told me not to change my ways. They said they understood me. But the thing is, now that I’ve viewed myself from their perspective, I’m not sure I want to remain the same. Change isn’t a bad thing. And since moving to Finland two years ago, I’ve kicked a few bad American habits.

Why the ingrained expectation that women should desire to become parents is unhealthy

In 2008, Nebraska decriminalized child abandonment. The move was part of a "safe haven" law designed to address increased rates of infanticide in the state. Like other safe-haven laws, parents in Nebraska who felt unprepared to care for their babies could drop them off in a designated location without fear of arrest and prosecution. But legislators made a major logistical error: They failed to implement an age limitation for dropped-off children.

Within just weeks of the law passing, parents started dropping off their kids. But here's the rub: None of them were infants. A couple of months in, 36 children had been left in state hospitals and police stations. Twenty-two of the children were over 13 years old. A 51-year-old grandmother dropped off a 12-year-old boy. One father dropped off his entire family -- nine children from ages one to 17. Others drove from neighboring states to drop off their children once they heard that they could abandon them without repercussion.

Trinidad has the highest rate of Islamic State recruitment in the Western hemisphere. How did this happen?

This summer, the so-called Islamic State published issue 15 of its online magazine Dabiq. In what has become a standard feature, it ran an interview with an ISIS foreign fighter. “When I was around twenty years old I would come to accept the religion of truth, Islam,” said Abu Sa’d at-Trinidadi, recalling how he had turned away from the Christian faith he was born into.

At-Trinidadi, as his nom de guerre suggests, is from the Caribbean island of Trinidad and Tobago (T&T), a country more readily associated with calypso and carnival than the “caliphate.” Asked if he had a message for “the Muslims of Trinidad,” he condemned his co-religionists at home for remaining in “a place where you have no honor and are forced to live in humiliation, subjugated by the disbelievers.” More chillingly, he urged Muslims in T&T to wage jihad against their fellow citizens: “Terrify the disbelievers in their own homes and make their streets run with their blood.”

The same part of the brain that allows us to step into the shoes of others also helps us restrain ourselves.

You’ve likely seen the video before: a stream of kids, confronted with a single, alluring marshmallow. If they can resist eating it for 15 minutes, they’ll get two. Some do. Others cave almost immediately.

This “Marshmallow Test,” first conducted in the 1960s, perfectly illustrates the ongoing war between impulsivity and self-control. The kids have to tamp down their immediate desires and focus on long-term goals—an ability that correlates with their later health, wealth, and academic success, and that is supposedly controlled by the front part of the brain. But a new study by Alexander Soutschek at the University of Zurich suggests that self-control is also influenced by another brain region—and one that casts this ability in a different light.

A professor of cognitive science argues that the world is nothing like the one we experience through our senses.

As we go about our daily lives, we tend to assume that our perceptions—sights, sounds, textures, tastes—are an accurate portrayal of the real world. Sure, when we stop and think about it—or when we find ourselves fooled by a perceptual illusion—we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.

Should you drink more coffee? Should you take melatonin? Can you train yourself to need less sleep? A physician’s guide to sleep in a stressful age.

During residency, Iworked hospital shifts that could last 36 hours, without sleep, often without breaks of more than a few minutes. Even writing this now, it sounds to me like I’m bragging or laying claim to some fortitude of character. I can’t think of another type of self-injury that might be similarly lauded, except maybe binge drinking. Technically the shifts were 30 hours, the mandatory limit imposed by the Accreditation Council for Graduate Medical Education, but we stayed longer because people kept getting sick. Being a doctor is supposed to be about putting other people’s needs before your own. Our job was to power through.

The shifts usually felt shorter than they were, because they were so hectic. There was always a new patient in the emergency room who needed to be admitted, or a staff member on the eighth floor (which was full of late-stage terminally ill people) who needed me to fill out a death certificate. Sleep deprivation manifested as bouts of anger and despair mixed in with some euphoria, along with other sensations I’ve not had before or since. I remember once sitting with the family of a patient in critical condition, discussing an advance directive—the terms defining what the patient would want done were his heart to stop, which seemed likely to happen at any minute. Would he want to have chest compressions, electrical shocks, a breathing tube? In the middle of this, I had to look straight down at the chart in my lap, because I was laughing. This was the least funny scenario possible. I was experiencing a physical reaction unrelated to anything I knew to be happening in my mind. There is a type of seizure, called a gelastic seizure, during which the seizing person appears to be laughing—but I don’t think that was it. I think it was plain old delirium. It was mortifying, though no one seemed to notice.

“All the world has failed us,” a resident of the Syrian city of Aleppo told the BBC this week, via a WhatsApp audio message. “The city is dying. Rapidly by bombardment, and slowly by hunger and fear of the advance of the Assad regime.”

In recent weeks, the Syrian military, backed by Russian air power and Iran-affiliated militias, has swiftly retaken most of eastern Aleppo, the last major urban stronghold of rebel forces in Syria. Tens of thousands of besieged civilians are struggling to survive and escape the fighting, amid talk of a rebel retreat. One of the oldest continuously inhabited cities on earth, the city of the Silk Road and the Great Mosque, of muwashshah and kibbeh with quince, of the White Helmets and Omran Daqneesh, is poised to fall to Bashar al-Assad and his benefactors in Moscow and Tehran, after a savage four-year stalemate. Syria’s president, who has overseen a war that has left hundreds of thousands of his compatriots dead, will inherit a city robbed of its human potential and reduced to rubble.

Even in big cities like Tokyo, small children take the subway and run errands by themselves. The reason has a lot to do with group dynamics.

It’s a common sight on Japanese mass transit: Children troop through train cars, singly or in small groups, looking for seats.

They wear knee socks, polished patent-leather shoes, and plaid jumpers, with wide-brimmed hats fastened under the chin and train passes pinned to their backpacks. The kids are as young as 6 or 7, on their way to and from school, and there is nary a guardian in sight.

A popular television show called Hajimete no Otsukai, or My First Errand, features children as young as two or three being sent out to do a task for their family. As they tentatively make their way to the greengrocer or bakery, their progress is secretly filmed by a camera crew. The show has been running for more than 25 years.

A recent study shows that people who simply ate more fiber lost about as much weight as those who went on a complicated diet.

By this time of year, many peoples’ best-laid New Year’s Resolutions have died, just seven short weeks after they were born. One reason why it’s difficult to lose weight—the most common resolution—is that dieting is so confusing.

For instance, the American Heart Association's recommended diet is one of the most effective food plans out there. It’s also one of the most complicated. It requires, according to a recent study, “consuming vegetables and fruits; eating whole grains and high-fiber foods; eating fish twice weekly; consuming lean animal and vegetable proteins; reducing intake of sugary beverages; minimizing sugar and sodium intake; and maintaining moderate to no alcohol intake.” On top of that, adherents should derive half of their calories from carbs, a fifth from protein, and the rest from fat—except just 7 percent should be saturated fat. (Perhaps the goal is to keep people busy doing long division so they don't have time to eat food.)
